The latest macOS, or operating system for Apple computers, is called macOS Big Sur. It was released in November 2020 and features an updated look with new icons and design elements, as well as improvements to built-in apps and performance enhancements.

The Evolution of Mac OS

Apple’s operating system, Mac OS, has evolved through the years. From the first version, System 1, released in 1984, to the present day, it has undergone significant changes in design, functionality, and features. With each iteration, Apple has introduced new features and improvements to enhance user experience, security, and performance. One of the most exciting features of each new macOS version is its name, which has always been inspired by California’s natural beauty and landmarks.

The Early Years

The first version of Apple’s operating system was called System 1. It was a bare-bones system that could only support a limited number of applications. Apple released versions 2 through 7, each with significant improvements and new features. In 1999, Apple released Mac OS 8, which marked a significant departure from the previous versions. It introduced a more modern interface, improved stability, and support for more third-party software.

The Transition to Mac OS X

In 2001, Apple released Mac OS X, which was a complete overhaul of the Mac operating system. It was built on a Unix-based architecture, making it more stable and secure than its predecessors. Mac OS X introduced new features such as the Dock, Spotlight, and Dashboard. It also marked the beginning of the naming convention that Apple continues to use for its operating systems.

The most noticeable change is the redesign of the user interface, which is now more modern and streamlined.

The Name

As with previous versions of macOS, Apple has continued its tradition of naming its latest operating system after a California landmark. Big Sur is a rugged stretch of coastline in central California known for its beauty and natural power. The name reflects Apple’s desire to capture the essence of California’s natural landmarks in its products.


Apple has also made significant improvements to the Maps app in Big Sur. The app now includes detailed maps of indoor spaces, such as airports and shopping malls. It also includes new features such as Guides, which provide curated lists of places to visit in a specific city. Users can also create their own custom guides and share them with others.
